Spontaneous polarized phase transitions and symmetry breaking in the imbalanced Dicke model
Jinling Lian, Ran Huang, Chao Gao +3
We investigate the ground-state properties and quantum phase transitions of an ensemble consisting of four-level atoms within an optical cavity coupled to the single cavity mod…
Two-dimensional topological effect in a transmon qubit array with tunable couplings
Yan-Jun Zhao, Yu-Qi Wang, Yang Xue +4
We investigate a square-lattice architecture of superconducting transmon qubits with inter-qubit interactions mediated by inductive couplers. Therein, the inductive couling between…
Logarithmic light cone, slow entanglement growth, and quantum memory
Yu Zeng, Alioscia Hamma, Yu-Ran Zhang +4
Effective light cones, characterized by Lieb-Robinson bounds, emerge in nonrelativistic local quantum systems. Here, we present several analytical results derived from logarithmic…
An Important Properties of Entanglement: Pairwise Entanglement can Only be Transferred by Entangled Pair
Xiao-Qiang Xi, W. M. Liu
Basing on the calculation of all the pairwise entanglement in the ()-qubit Heisenberg XX open chain with system impurity, we find an important result: pairwise entang…
Pairwise Entanglement and Local Polarization of Heisenberg Model
Xiao-Qiang Xi, R. H. Yue, W. M. Liu
The pairwise entanglement and local polarization of the ground state are discussed by studying the Heisenberg XX model in finite qubit case. The results show that: the ground state…
